No sane person is calling for Mueller to recuse himself. Only a true numbskull would tell someone to step down towards the END of his investigation.
Even the leftist USA Today has called for Mueller to do the honorable thing;
{Robert Mueller is a man of integrity with a long record of public service. In the abstract, he would be the right selection as special counsel in the Russia investigation. Under the specific circumstances of this case, however, with his longtime friend
James Comey at the center of the inquiry, Mueller's the wrong choice. The public cannot be as sure as it needs to be of his objectivity.
This is true for reasons similar to those that prompted Attorney General Jeff Sessions to recuse himself from the same investigation. Sessions testified Tuesday that he felt he had no proper choice because he had a potential political conflict of interest, having been a campaign adviser to President Trump. Mueller should likewise step away because he has a potential personal conflict of interest, having been a longtime friend of a crucial witness, Comey, and Comey's key ally at the most important moment of his career.}
Robert Mueller should recuse himself from Russia investigation
The problem is of course, Mueller has no honor. He is a leftist hack.
